The electrolyte is one of the three essential constituents of a Lithium-Ion battery (LiB) in addition to the anode and cathode. During increasingly high power and high current charging and discharging, the requirement for the electrolyte becomes more strict. Solid State Electrolyte (SSE) sees its niche for high power applications due to its ability to suppress concentration polarization and otherwise stable properties also related to safety. During high power and high current cycling, heat management becomes more important and thermal conductivity measurements are needed. In this work, thermal conductivity was measured for three types of solid state electrolytes: Li 7 La 3 Zr 2 O 12 (LLZO), Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 (LAGP), and Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) at different compaction pressures. LAGP and LATP were measured after sintering, and LLZO was measured before and after sintering the sample material. Thermal conductivity for the sintered electrolytes was measured to 0.470 ± 0.009 WK − 1 m − 1 , 0.5 ± 0.2 WK − 1 m − 1 and 0.49 ± 0.02 WK − 1 m − 1 for LLZO, LAGP, and LATP respectively. Before sintering, LLZO showed a thermal conductivity of 0.22 ± 0.02 WK − 1 m − 1 . An analytical temperature distribution model for a battery stack of 24 cells shows temperature differences between battery center and edge of 1–2 K for standard liquid electrolytes and 7–9 K for solid state electrolytes, both at the same C-rate of four.

“…There are strong needs for advanced BMS that have real-time access to both local and distributed temperature information of each battery cell, enabling more precise estimations of SOC and RUL, as well as early detection and prevention of catastrophic events such as thermal runaway. Various sensing principles have been employed and developed in the past decade including but not limited to resistive sensors [13], thermoelectric sensors [14], infrared thermography [15], electrochemical impedance measurement [16], giant magnetoresistance (GMR) based Johnson noise thermometry (JNT) sensor [17], and fiber Bragg grating sensors [18]. These sensors are either utilized for direct temperature measurements at the desired locations or combined with physics-based or data-driven modelling methods for estimation of other key parameters.…”

“…These sensors are either utilized for direct temperature measurements at the desired locations or combined with physics-based or data-driven modelling methods for estimation of other key parameters. Non-commercially available sensors are also designed and fabricated by Screen Printing [13], or Micro-electro-mechanical-systems (MEMS) fabrication techniques [15] for higher spatial and temporal resolution, easier assembly, or lower cost. Challenges remain in the design and manufacturing of low cost, compact, non-intrusive, and high dynamic range (i.e.…”

Lithium-ion batteries have been widely used as energy storage for electric vehicles (EV) due to their high power density and long lifetime. The high capacity and large quantity of battery cells in EV as well as the high standards of vehicle safety and reliability call for the agile and adaptive battery management system (BMS). BMS is one of the key technologies for electric vehicle development, which contributes to the overall performance of lithium-ion batteries in operations. Through a comprehensive literature review, this paper presents a review of lithium-ion battery management systems, including the main measurement parameters within a BMS, state estimation methods, cell equalization issues, thermal management strategies and research trends and progresses. The paper discusses and highlights the key elements and challenges with recommendations in terms of the development of next generation BMS technologies.
